There are many variations of this, but here's the version I have in my recipe box:
Tater Tot Hotdish
Serves 4-6
1 lb of lean ground beef
1 lb bag of tater tots
2 10-ounce cans of condensed cream of mushroom soup
14 ounce can of vegetables of your choice (corn is often used; I prefer peas and carrots)
2 cups of cheddar cheese
Preheat oven to 350 degrees. While it's preheating, brown and drain beef. In a 2.5 quart casserole dish, layer beef, drained vegetables, soup mix (don't add water to this!), and tater tots. Bake uncovered for 40 minutes. Remove from oven; top with cheese. Bake for 10 minutes longer.
A Note From Bethany...
To make this recipe lower in fat, I use low sodium cream of mushroom soup. Some versions also use turkey in place of beef. I also use a lower fat sharp cheddar cheese made with 2% milk. (Some versions of the recipe omit it entirely). It won't make it a health food by any means, but it'll help cut down on the guilt!
